Spending about 180 hours in this game, I can say it becomes addictive at some point. The concept of being a Class 3 civilization sending just a mecha to do the dirty work for you is nonetheless fun.

The game starts with the basic idea of collecting resources, building factories and, researching advanced technology leading to the construction of the Dyson Sphere but, the game doesn't just end after that. As you will notice, when you start the game, you start with a star cluster, depending on how many stars you choose. You will have a variety of planets and stars to discover, which is a good exploration element. The beauty of the game is just mesmerizing. And, I found the correctness of the scientific details up to the mark.

The game itself isn't complicated. But it'll take some planning, hit and trial and efforts to gather the resources you need and keep the factories running. The game won't feel like a grind if you can manage a constant flow of resources in all the factories. It'll teach you about pipelining and logistic techniques.

So the review about the game:-
A Building Simulation
Infinite Playtime
Factory Based Game
Have Exploration Element
No Story Line
Good Graphics
Heavy on FPS late game
Unofficial Mods Available
No Bugs
Constantly Updated
Have Multiplayer with Mods

About Mods, you can have them through r2modman but use it at your own risk. There are no bugs in the base game but, modding might introduce some. There are no issues with the game itself.

So, I recommend you to buy it even at its native price (do support the devs and not wait for a discount). Spend a few good hours on the game before judging it and, kindly don't buy the game if you are not into Building or factory simulations, LOL. It's still in early access but at its best right now. Let us see what the future holds. I'm keeping my fingers crossed and hope this game grows as it is right now and doesn't lose its essence. It's my 1st review ever so, don't judge harshly.

Love the complexity of the game when it comes to manage the railways in large map. Very closely resembles real life traffic except one thing which i would love to see, set priority for trains so that they can pass through the slower once. The modding community is one of best so don't be shy to have hell lot of mods of your choice.

The game might feel slow and very effort taking if you're playing a large map to construct and start the railways to work well but it's worth the wait and efforts when you see the output.

One bad thing about the game is the absence of Day Night cycle due to the game design and the time cycle system. Will love to see where the game time is not dependent on years but number of days top open things and one day can pass on 5 mins or so with a Day night Cycle and some weather effects over the transportation. May be some disaster incidents?
